GROSS-JOINTED METAL BAR.

Application filed March 18, 1925.

This invention relates to cross-jointed metal bars and particularly to a oint structure for metal window sashes, metal doors carrying panes of glass and other structures and has for an object to provide a construction which will present a maximum strength and a pleasing appearance.

Another object in view is to provide a joint structure for metal bars wherein none of the metal is removed or a minimum amount is removed.

A further object of the invention is to provide a cross-joint structure for bars for metal window sashes and the like wherein part of one bar is cut and pressed into a bracing and holding member interlocking with certain parts of the crossing bar.

In the accompanying drawings Figure 1 is an elevation of a metallic window sash showing other cross-joints embodying the invention.

Figure 2 is an enlarged elevation of: one of the cross-joints shown in Figure 1.

Figure 3 is a side view of the vertical bar shown in Figure 2 before the pressed out portion has been formed into its final shape. Figure 4is a sectional view through Figure 2, on line 4--t.

Figure 5 is a sectional view through Figure 2, on line 55.

Figure 6 is a perspective view of the interlocking part of the bar shown in Figure 2 illustrating how the same is formed to receive the cross bar.

Figure 7 is a view similar to Figure 5 but showing a modified construction, the same being taken approximately on line. 77 of Figure 8.

Figure 8 is a view similar to Figure 4 but showing a modified construction.

Figure 9 is a view similar to Figure 8 but showing a further modified construction.

Figure 10 is a top plan view of Figure 9.

Figure 11 is asectional view through Figure 9, approximately on line 1111.

Referring to the accompanying drawings by numerals, 1 indicates a metal frame of any desired kind having cross bars 2 and 3 for assisting the frame 1" in holding the different panes of glass 4 in proper position. Heretofore, various methods have been provided for interlocking and connecting together at the point of crossing the bar 3 with the various bars 2. In the present ine si s ved a sag h s been 9 9* Serial No. 16,450.

vided shown in its complete working condition in Figures 2, 4t and 5.

From Figure 3 the bar 2 is shown after it leaves the first die or punch. In this condition, a section 5 is pressed away from the web 6 for forming a socket 7. The section is cut out of the web 6 to form the slot 8 and a portion is pressed out of the web at point 9 for forming the bracing members 10 and 11 which are integral as they are pressed from the same piece of material. After the parts have been thus formed, the bar 3 is forced into position as shown in dotted lines in Figure 3 and then a die is used for pressing and forming the apex or connecting portion 12 until the stiffening and gripping channel 13 is formed and is caused to press against the edge of the web of bar 3 and also against part of the sides thereof.

When the parts are in the position shown in Figures 2 and 4;, the bar 3 is held rigidly in place without any auxiliary holding means. It will be noted that in forming this cross-joint, the only metal actually removed is that which is removed to form the slot 8. By this method of construction, the crossjoint has almost one hundred per cent of metal left in place and acting to brace or stiffen the joint. From Figures 3, 4 and 6, it will be noticed that the line of severance 14: is about centrally of the web 6 but if desired, this'line could be raised or lowered in respect to the base 15 of bar 2 without departing from the spirit of the invention.

In the form of the invention shown in Figures 2 to 6, the gripping member 13 projects above the web of bar 2 for approximately the thickness of the metal. Under some circumstances it is desired to make the structure so that the upper edge of the gripping member 11 will be flush with the edge of the bar 2. When this is the case the parts are constructed as shown particularly in Figures 7 and 8. From these figures it will be noted that the bar 3 is formed with a notch 16 which is adapted to receive the gripping member 13' which is formed in exactly the same manner as gripping member 13 but. is pressed downwardly until it assumes the position shown in Figure 8. In constructing this form of the invention, the portion or apex 12 must be raised substantially to the position shown in Figure 3 in order that bar 3 of Figure 7 may pass through until notch '16 is in a correct positin ' the sides ei t tion after which the gripping member 13 may b termed and may be pushed down into the notch 16 until the parts are flush as shown in Figure 8; This positively locks all the parts together and also presents a stiffened and braced striicture at the cros joint which heretofore has been the weakest part of the window sash.

In Figures 9, 10 and 11, a further modified form of the invention is shown in which a bet 3' having a face of it different shape is shown though the same form of base as shown in Figii're 4; might be used with this fern of the invention; In this form of the iii-Mention, e web is cut from the base along the line 17 and is formed into the bracing members 10' and 11 after which the gripping Iheinber 13 is pres'sedinto the desired shape the desired position In this form of the invention, none of the material or either her is removed and; eenseqiiehtl this present a ery strong and rigid tress-joint which retains one hundred per cent of the material of which the bars are made. It is evident that other forms cf the invention might be made without departin from the spirit at the invention, theessehtieii rinciple remaining the same. Heretofhr' either one or both bhis have been notched and the sits ittet'ld ked either with or without some orm seldei eh fastening means. in the preseflt ii'wntidfi very little or none of the metal is entirely removed hilt; on the contrary, a nation of the of the bars is pushed to one side and termed into' gripping and hreeiii members for not only bracing the bar on which the members ar termed but the cross bar ethaetih therewith.
